PROCESS AND APPARATUS FOR MAKING RESIN AND TURPENTINE.

ms for the .manufacture of pure turpentine and resin which will be refined and free from any foreign substance, and at the same time be economical inthe manufacture and in which the machineryand apparatus Wlll be simple and easy of construction and operation. y We obtain these objects by means of the apparatus shown in the accompanying drawings, whichconsists of a side elevation of the apparatus, partly in section, showing the system of construction and use.

Figure 1'. is a continuation of Fig. 1.

, Similar numerals refer to similar parts throughout the several views. Referring to Fig. 1 of the drawings:

1 is a tank or boiler into which they crude "turpentine is placed; the tank 1 is provided with a double bottom so as to form a space =52 adapted to contain steam to'heat the mass 85 in the tank.

For the purpose of filling or cleaning, a suitable man hole 2 is rovided at or near the top. In the interior, of the tank is rnounted on suitable supports, 10*10 the shaft 10 carrying the blades:9 9 which are adapted to agitate the mass in the tank.

- The lower blades are preferably curved to conform to the contour, of theta'nk bottom. On the upper end of the-shaft 10 is mounted the bevel gear 11 adapted to engage the bevel gear 12 on the shaft 13. The shaft 13 being provided with the hand wheel 14, by

, which it may be operated; As thus arranged the blades may be caused to operate 60 and stir the mass in the tank byturning the hand wheel '14. Inside the tank is also mounted a pipe or spur 7 provided with perforations 8'-8.

bottom is arranged the passage way 15 leading into a. receptacle 16 provided with a tray 87. The tr: iy 87 is preferably tapered and operated by the hand Wheel and screw 62, or in any suii able manner, so that it can be forced into the receptacle 16 to make a tight fit and prevent leakage.

To heat the ta. 1k 1, and the masstherein, steam from pipe 3, connected with any source of supply, is conducted through the pipe 4 and control valve 58 into the space 52,; space 52 is provided with a drip valve 17' to, draw eff co ndensations.

a To add additional heat and moisture to the mass steam may be admitted from steam pipe 3 through pipe 5 and "alve 59 into the spur 7 and thercethrough the ports 8-8 directly into the mass. Thus arranged, the Y crude turpentine is placed in the tank 1, steam supplied, and when the mass reaches the required temperature some of the turpentine in the nass will vaporizeand pass through the tube 18 and pipe 19 into the condenser coil 57 :11 id. thence into the tank ,23.

At the same timz steam is shut off at valve 59. The. condenser coil is mounted in the tank '20; the tank 20 being arranged so as to be supplied with cold water from the cold water main 22 through pipe 21 and control cock 61. ,At or near thetop of the tank is arranged an overflow 56.

The tank 23 is provided with a siphon pipe 55 and overflow 54.

The tank 1 is iupplied with suitable gage or thermometer .33.

When the mass has ceased to vaporize the liquid contents {re drawn ofl by means of valves and condictors 24--25 into the steam heated filter tark 26. The residue which settles to the boti om of the tank is drawn off through the pas: iage way 15 into receptacle 16, as desired.

The tank 26 is provided with a filter screen 60 and is arranged to .be heated by admitting steam from steam main 3 through pipe 50 and valve 88 into space 51 ,formed'in bottom of tank 26. The space 51 i is provided with a drip cock 27 to permit water of condensation being drawn off. The

liquid in tank 2b is then drawn oil through valve 28 and passed through the screened funnel 30 into tank 29. Referring to Iig. 1':

After the liquid has been placed in tank 2!) the cock 89, Fig. 1, is closed and steam admitted from the steam main ll through the valve Tl) into the top ol' the tank. The steam pressure will loree the liquidthrough the pipe 31. which extends nearly to the bottom of tank and is open at its end, through the valve 75 and pipe 52. Fig. 1, into the tank 323. The tank 253 has an outer jacket Slforming a steam space (3.7 and is provided with a plurality of llues Ti -J2 to provide additional heating surface that the liquid in the tank may be quickly raised to the. right temperature. A thermometer To is pro vided to register the temperature. Steam from the steam main 23 is admitted by means of the pipe (37 and control valve ()8 into the steam space (15 and flues 72 72. gage i? being provided to register the pressure in the steam space. i

In order to further stimulate vaporization steam may be taken from the steam space 65 and admitted through the loop T 3, valve 74, and spurs T1T1. A suitable drip cock 75 is provided at the bottom of the loop.

The vapor resulting will pass through the tube 34 into the tubes )0 in the cooling box 35, thence through the tube so into the coudenser coil 86 in the tank 3T, and thence into the tank 38.

Cooling tank 35 is supplied with water from water main 22 through pipe. 79 and Cock 79 and provided with overflow and control cock 80. Tank 37 is supplied with water from \vater-nmin 22 through pipe 30 and control valve 91 and has an overflow at or near the top.

Tank 381s similar to tank having overflow 81 and siphon draw off 82.

The tank 39 has hand hole (ii for clcaning. Tank 33 has passage way 40 leading through steam space (35 into receptacle 41, which has a tray operated by a hand wheel 83 the same as receptacle under tank 1. Through this passage way 40 and receptacle 41 the resin is removed from the. tank after the turpentine has been extracted.

The operation of our apparatus is as follows: The crude turpentine is deposited in tank 1, which is a melting boiler, wherein it is heated by injected steam and the mass agitated in a heated condition, as already described. \Vhen thus heated some of the turpentine will be vaporized and pass through cooling tanks and may be drawn ofi'.

This turpentine will only be a small quantity and of poor quality and color. "Vhen the crude turpentine is melted the steam is shut ofi from the mass in the boiler. The liquid is then drawn off from the other side of tank 1 through faucets located at ditlerent elevations in tank 1, the higher elevation is clearer and drawn ofi first while the impurities are settling to the bottom and drawn .off through the outlet in the. bottom. The liquid drawn from tank 1 passes through Va:

rious filters into tank 29. The filters and tank receptacles'arc kept heated by steam pipes under them. Steam is then conducted into the top of tank 29 and forces the liquid from near the bottom of tank 29 through a pipe into the upper part of tank 33. The liquid is subjected to much more intense heat in tank 33 and the turpentine. is vaporized and passes in the vaporized form from the top of the tank through a cooling system and condensed to a liquid form and collected in the liquid form in a final tank from which it is drawn off into receiving receptacles. The resin, in the meanwhile, settles in the bottom of tank 33 and is drawn off from the bottom of the tank.

\Vhen constructed in this way the tur-- pentinc and resin will be of the best quality, sparkling and free from any impurities or foreign matter. The machinery and apparatus required may be economically constructed and operated and withoutthe use of lime water or oxygen or other chemicals will rapidly transform the crude turpentine into pure and refined turpentine and resin without loss in materials. Much more turpentine and resin may be manufactured by this system than in any other way and in much less time.

\Vhat we claim as our invention and de sire to secure by Letters Patent is 1. The above described process of manufacturing refined turpentine and resin by placing the crude turpentine intoa tank, heating the mass in the tank by injected steam, agitating the mass while in a heated condition within the said tank, drawing the liquid from the tank at diiierent levels, filtering the liquid when drawn from the tank, forcing it by steam pressure applied'to the upper surface of the liquid through conductors into another tank, while the liquid is still heated, reducing said liquid to vapor by steam heat in the second named tank, conveying the vapor from said second named tank through cooling apparatus whereby the same may be condensed again into liquid form, and taking the resin from the bottom of said last named tank through an opening in the bottom thereof.
